The Wishing Well Cluster (NGC 3532) is 1.500 lightyears away in the constellation Carina. The name comes from the visual appearance of a handful silver coins thrown into a well for good luck. This open cluster was first catalogued by Nicolas Louis de Lacaille in 1751 from his observatory at the Cape of Good Hope. John Herschel wrote "the most brilliant object of the kind I have ever seen". NGC 3532 is indeed one of the richest Galactic open clusters with over 1.000 stars and an estimated age of 300 Myrs.
